Help with Programming (arduino)

Hi LMR,

I've been working on my new robot, which has a lynxmotion A4WD1 base with an arduino as its microcontroller. I must confess that I am not the best programmer and I am still learning. I have found the follow code online and I was wondering if anyone could help me adjust it to be able to turn left and right. As of right now the program only tells the motors to go foward or reverse at full speed or half speed. The code:

 

 #include <SoftwareSerial.h>

Face Tracking with Processing and Arduino

I was wondering if anyone can help me with my code. So I am using my camera on my macbook pro. In processing, the tracking software works almost perfectly, I am using opencv. Then through serial the coordinates of my face are supposed to be translated to servo commands and sent to the arduino. I am getting movement with the servo, but it is only jitters. Any help is well appreciated. 

Processing Code:

 

import hypermedia.video.*;

import java.awt.Rectangle;

import processing.serial.*;        

 

 

Adafruit motor shield, just running one motor

I have looked at the tutorials from adafruit, such as this one:  http://www.ladyada.net/make/mshield/use.html and I can include the library in my program, I tried the examples and I get nothing. I am using 7.2 volts for my power supply and the motor is from an rc car. I have tested the motors with a different h-bridge that came with my DFrobotshop rover and it works fine.
